靶點詳情

功能：

Component of the spliceosomal U1 snRNP, which is essential for recognition of the pre-mRNA 5' splice-site and the subsequent assembly of the spliceosome. SNRNP70 binds to the loop I region of U1-snRNA.; Truncated isoforms that lack the RRM domain cannot bind U1-snRNA.; Truncated isoforms that lack the RRM domain cannot bind U1-snRNA.

1. These results indicate that the galectin-3-U1 snRNP-pre-mRNA ternary complex is a functional E complex and that U1 snRNP is required to assemble galectin-3 onto an active spliceosome PMID: 27105840
2. The epitopes of U1-70K autoantibodies have been mapped at single-amino acid resolution. PMID: 26333287

16. data identify some fungal proteins as possible triggers of anti-U1-70 kDa autoimmunity via molecular mimicry. PMID: 21348812
17. the hypo-phosphorylated RS domain of SRSF1 interacts with its own RRM, thus competing with U1-70K binding, whereas the hyper-phosphorylated RS domain permits the formation of a ternary complex containing ESE, an SR protein, and U1 snRNP PMID: 21536904
